To ensure consistency in its supply chain processes, the U.S. Department of Defense put into place a system that uniquely and permanently identifies the items that it purchases. This system, dubbed the National Stock Number (NSN), consists of 13 digits which are broken down into the 2 following identifying parts:

Federal Supply Classification Group - The first 4 digits of the NSN identifies the Federal Supply Class code (FSCG).

National Item Identification Number - The last 9 digits of the NSN identifies the National Item Identification Number (NIIN).

For example, an existing blade has a 13-digit NSN of 38-05-00-0092148. The FSCG is represented by 3805, and the NIIN by 000092148.

Furthermore, the FSCG and NIIN can be broken down even further into the following classifying parts:

In the above blade example, the FSG is represented by 38, and the FSC by 05.

In the above blade example, the NCB is represented by 00 (USA).

Federal Supply Group - The first 2 digits of the FSCG identifies the Federal Supply Group (FSG).

National Codification Bureau - The first 2 digits of the NIIN identifies the National Codification Bureau (NCB) or NATO country code.

Item Serial Number - The last 7 digits of the NIIN is merely an item serial number that does not follow an assignment pattern.
